DOOR-FASTENING FOR MOTOR-CARS, CARRIAGES, AND OTHER VEHICLES.

; Specification of Letters Patent.

Application filed August 11, 1915. Serial No. 44,903.

To all whom it may concern:

Be it known that 1, JAMES CHARLES BALLS, subject of England, residing at30 Hampton road, Shefiield, in the county of York, England, haveinvented new and useful Improvements in Door-Fastenings for Motor-Cars,Carriages, and other Vehicles,

of which the following is a specification.

This invention relates to a door fastening for motor cars and carriagesand other vehicles, and has for its object, in addition to the ordinaryslam latch bolt, the provision of asafety grip device, combining utilityand reliability with simplicity of construction. My improved doorfastening has an advantage overthe ordinary type of carriage doorfastenings inasmuch as it provides an extra grip, which insures a.secure locking action by means of turning the handle a quarter of a turnmore from its normal position. These advantages, in combination with theordinary spring latch action render my invention of special value as itgives to the traveling public greater security than with the carriagedoor fastenings of the ordinary type. It should here be stated that this1nvention is not claimed in connection with safe looks, not beingsuitable for use in connection with stationary objects such as steel oriron safes, and pertains only to the temporary fastening of the doors ofcars, carriages and the like moving vehicles.

My invention will be better understood on reference to the accompanyingsheet of drawings in which,

Figure 1, is a side view of my improved fastening in its normal positionto act as a slam latch.

Fig. 2, is an end view of the striking plate employed with my improvedfastening.

Fig. 2, is an underside view of same.

Fig. 3, is a similar view to Fig. 1, but showing the bolt of thefastening locked in engagement with the striking plate.

Fig. 4:, is a further view showing the bolt entirely withdrawn into thecasing.

Fig. 5, is a right hand end view of Fig. 4.

The same letters refer to similar parts throughout the several views.

According to my invention I construct my improved car or carriage doorfastening with a beveled head spring-slam latch bolt, I), with a sidegrip, a which is made by an extension on the underside of the beveledbolt head, a, of the bolt, 7), (not a deadsquare-head as others lockedwith a key) for gripping the door. and its doorpost together,

without a key as hereinafterdescribed. The

bolt, Z), is formed with, an opening, 6 for the reception of a singlearmed follow, 0, the

arm, d, of which as it is moved under the in,-

fluence of the door handle, .a'ctuates the bolt when it bears upon thelug, 6 ,(to withdrawthe bolt) or-fiange, b of ,the said bolt (to buttlock it). Any suitable form of spring or springs may be employed inconnection with my invention, but by preference I em ply a double armedwire spring, h, the vertical arm, 5, of which giving a forward movementtothe bolt, and the horizontal arm, 71, lifting the 'bolt and keeping itinv the upper part of the bolt hole, y, in the front plate, j, ofthe.casing, in its normal position for the slamming action. The bolt, Z), isguided in its backward and forward and up and down-movements by means ofpins, 6, e, e, e, secured to the casing, moving in right angled slots f,",-f, formed in the bolt itself.

In Fig. 1 of the drawings, the bolt is shown in its normal position,when it would act as a slam latch and would be self-operating when thedoor to which my improved fastening was attached, was pushed or slammedto. l/Vhen it is desired to securely fasten the door in its closedposition, the follow, 0, and arm, d, would be turned to the positionshown in Fig. 3, whereby the grip a on the head, 0;, of the bolt, (2, isforced downward against the action of the horizontal arm, 71?, of thespring, 7L, and effectively locks the door to the side post by reason ofthe grip,-0; passing down behind the portion, 71 of the striking plate,2'. It will be observed that when in this position the pins, 6, are atthe upper ends of the vertical portions of the slots, 7, and the followarm, cl, is directly under its pivoted center and at right angles to theflange, b so that it cannot be released by the motion of the vehicle orany other similar cause. On the door handle being turned upward to theright the follow arm, cl, is withdrawn and the bolt is forced upward bythe horizontal arm, 7L2, of the spring, 72.. By a further quarter turnof the handle the bolt can be drawn back into the casing (preparatory toopening the door) by means of the follow arm, d, engaging with the lug,g, (as shown in Fig. 4) and in this case it Will be seen that the pins,6, are at the extreme. forward ends of the horizontal portions of theslots, f.

The form of striking plate I employ in connection with my invention isshown in Fig. 2, wherein it will be seen that the lower portion, '5 ismade longer than in ordinary striking plates, in order to receive.the.extension, [4 of the bolt head, a, when ina gripped and locked position.

Having now described my invention, what I claim as new and desire tosecure byLetters Patent, is

1. In door fastenings for motor cars, carriages, and other vehicles, theimproved formation and construction, comprising a bolt head providedwith an extension on its underside to grip the striking plate of thedoor post, a bolt having right angled slots engaging with fixed pins onthe casing, and

having a central opening provided with a depending lug and a flange, asingle armed follow adapted toengagew'ith said lug and flange, and adouble armed spring to give a forward and also an upward movement to thebolt, substantially as herein described and illustrated on theaccompanying draw: ings.

2. In door fastenings for motor cars, car

riages, and other vehicles, the improved means, consisting of pins inthe casing, a bolt having right angled slotsengaglng sa d pins andadapted to move in right angular directions, and an extension on theunderside of the bolt head to engage behind the striking, plate whenuthesaid bolt is in its fastened position, substantially as herein describedand illustrated on the accompanying drawings.

3.111 a spring latch, a spring-slam latchbolt having ahead formed with adepending projection adapted to engage and hook over the striking plate,meansto normally hold the bolt in protracted position but free of hookengagement with the striking plate, and means for moving the bolt tocause the said projection to engage andhook over the striking plate. v

l. In a spring latch, a bolt, means for normally returning said boltautomatically to protracted 7 position, a projection on, the headof saidbolt at right angles to the direction of said motion, and ineans formove, ing said bolt in the direction of said projection whereby saidprojection engages the striking plate. and is positively 'held in ockedposition.
